I actually quite enjoyed it

What I liked:
-Cade was a likable character
-Lots of robot screen time
-Optimus was awesome and had his own mini story arch
-Dinobots were Badass
-Lockdown the villain was the best we've had
-A few emotional scenes (ratchets death and prime acknowledging it, cade caring for his daughter, the ending with prime and cade, few more)
-The autobots having individual unique character (I loved crosshairs)
-the serious tone
-Expanding on the transformers universe
-Galvatron was cool, but weak origin and needed more screen time and maybe interact with Lockdown
-Bad human characters were fearsome and pretty Badass
-"my face is my warrant" was bad but I couldn't stop laughing so I kinda like it haha

Things I didn't like:
-Tessa (at times) and her *beep* boyfriend
-rushed KSI plot (I do like the idea it was just executed poorly)
-Not explaining about Sam and the other autobots from TF3
-Dinobots not talking nor having much screen time
-Brains disappearing after explaining Galvatron
-The film was poorly edited
-Ending was very quick and bizarre.. Not enough time for the characters to interact and having closure
-Crosshairs not doing anything in the final battle... So disappointed
-The line "I'm not here to help save your daughter, you're here to save my girlfriend" pissed me off and made me wish cade threw him off the ship to his death
-Ling Ling or whatever her name was, was pointless and wasted plenty of screen time which should have been given to the autobots
-KSI bots turning into cubes.. Ok? (cool idea but the bots should have been a new race, not human built)

These were the main points, few other nick picks and that's it


I did enjoy the film though, deserves more than 17%(?) on rotten tomatoes
